The Solidbit ransomware is a newly discovered strain of file-encrypting malware.
Solidbit will encrypt most of the files found on the victim system, leaving files essential to the operation of Windows intact. However, documents, media files, archives and database files will be encrypted.
Once encryption of a file completes, the original file gets a new extension comprised of four ransom alphanumeric characters. This means that a file formerly called "document.docx" might turn into something like "document.docx.hdg9".
When the encryption process is finished, the Solidbit ransomware will drop its ransom note inside a file named "RESTORE-MY-FILES.txt". Along with this, a pop-up window is created and shown to the victim, informing them of the attack and offering an interface to contact the ransomware operator.
The full contents of the ransom note are as follows:
